What it detects
This rule detects HTTP requests carrying the malformed User-Agent string used in exploitation of PAN-OS CVE-2024-0012 and CVE-2024-9474. This behavior matches Operation Lunar Peek where attackers chained authentication bypass and privilege escalation against management interfaces. The distinctive rv 11.0 token differs from legitimate browsers and provides a reliable signature for exploit traffic against exposed firewalls.
